Abstract

This paper explores some conceptual and descriptive parallels between vocal and
non-vocal communication, paying particular attention to the physical phenomena
and semiotic functions in both speech and gesture. The discussion focuses on
the interplay between organic and performance components of speech and
gestural behaviour. A central thesis of the paper is that dilemmas of semiotic
attribution are likely to arise when a person's organic state constrains or alters
their communicative behaviour, especially if the listener or observer is unaware
of that organic state. This thesis is illustrated by a discussion of the changes in
communicative behaviour that may result from the physical modifications and
movement constraints that are typically associated with old age or with selected
disorders of movement. The paper concludes that a more integrated programme
of research into comparable descriptive and theoretical concepts would offer a
timely and fresh perspective on both speech and gesture, and their semiotic role
in conversational interaction.
